RNA Polymers

Midland?s catalogue contains carries several varieties of RNA Polymers and RNA template/primers. RNA Polymers (Polyribonucleotides) RNA Polymers are prepared by the catalytic action of the enzyme polynucleotide phosphorylase, isolated at Midland, and the appropriate, ribonucleoside diphosphate as substrate. With the exception of catalog number P-3102, RNA polymers are packaged by weight (mg).

RNA Template/Primers
Complexes of oligodeoxynucleotides with their complementary polymers are useful in distinguishing DNA polymerase activity from true reverse transcriptase.
MIDLAND offers both polydeoxyadenylate and polyriboadenylate annealed with oligothymidylates, p(dT)10 and p(dT)12-18. Similarly, oligo p(dG)12-18 is prepared by annealing the oligodeoxyguanylate with polycytidylate or polydeoxycytidylate. All complexes are equimolar and all are furnished as the lyophilized sodium salts.
Template/primers are packaged and sold on the basis of A260 Units.
